A sensor 5 is arranged above the connection between the conveyors 2 and 7, and a sensor 9 is arranged near the upstream end of the conveyor 10.

Next, the operation of the above configuration will be described. The foreign matter detector 1 is provided with a metal mechanical part or a broken piece thereof in the product 3 being conveyed in the direction of the arrow by the conveyer 2.
It is inspected whether foreign matter such as plastic fragments or hair is mixed, and when a foreign matter is detected, a detection signal is sent to the control device 4a in the console section 4. The control device 4a stores information for identifying the foreign matter-containing product, for example, the serial number of the product from the start of operation.

Next, the sensor 5 sends a detection signal to the control device 4a when the product 3 is conveyed to the conveyer conveyor 7 which constitutes the weighing conveyer 6. Control device 4a
Sends a weighing command signal to the weighing machine 8, and the weighing machine 8 constantly weighs the weight of the product 3 on the conveyor 7. The control device 4a receiving the detection signal from the sensor 5 sends the weighing signal. The processing circuit 4b is controlled to receive the detection signal from the sensor 5 and then take in the weighing signal from the weighing instrument 8 at a predetermined timing. The weighing signal processing circuit 4b determines whether the weight of the product 3 is within a predetermined allowable range, is over, or is under, and if it is over or under, the serial number of the product and the over number are over. Alternatively, a signal indicating under is sent to the control device 4b, and the control device 4a stores the data.

The sensor 9 detects that the product 3 conveyed to the conveyor 10 has reached a predetermined position, and sends a detection signal to the label printing / pasting device 11. FIG. 2 is a block diagram showing the configuration of the label printing / pasting device 11, and
The control means 11a is based on the weighted product, the overweight or the underweight of the product 3, which is given from the control device 4a of the console unit 4, that is, the information based on the detected weight of the product 3 and the information on the inclusion of foreign matter. , Control the print data by the label transport printing means 11c.

The operator manually removes the products labeled “foreign matter” on the label 12 and manually repacks the products labeled “overweight” and “underweight” on the label 12. Then, the gate 14a is opened and only normal products are shipped.

According to the first embodiment, when there is no foreign matter mixed, the label indicating "weight over" or "weight under", which is the information based on the weight, is displayed on the non-quantity product as the regular quantity ( (Passed product) is a label displaying the product name, price, weight, quality, etc.
On the other hand, a label indicating that fact is attached to the top surface of the product while the product is attached to the top surface of the product.
Therefore, in the subsequent process, it is possible to easily discriminate for what reason the defect is caused and deal with it. Also, by printing how many grams of deviation is printed for overweight or underweight, it is possible to easily readjust the upstream side weighing device by checking the tendency of the magnitude of the deviation.

Further, since the sorting conveyor (first sorting section) for removing the foreign matter mixed product from the transport line, which is provided in the conventional apparatus, can be omitted, the apparatus becomes compact, the apparatus price is reduced, and the apparatus is installed. The effect of narrowing the area can be obtained.

In the first embodiment, the storage conveyor 13 and the gate driving device 14 that cooperates with the storage conveyor 13 are provided, but this portion is not essential and may be a mere storage stand.

Further, in the first embodiment, the description has been given by taking the fixed-price product as an example, but it is obvious that the same can be applied to the non-fixed-price product in which the price is calculated according to the measured value and a different price is printed. is there.

FIG. 4 is a block diagram showing the configuration of the second embodiment of the present invention. Instead of the storage conveyor 13 and the gate driving device 14 of the first embodiment, a distribution gate 16 is provided on a transfer conveyor 15. Sorting conveyor device 17
Is installed. 4, the same reference numerals as those in FIG. 1 denote the same or corresponding portions.

The label printing / pasting device 11 prints on the label 12 based on the information of the acceptable product, overweight, underweight, and foreign matter mixture of the product 3 given from the control device 4a of the console unit 4. , Paste on product 3. The distribution control unit 18 of the distribution conveyor device 17 receives a command from the control device 4a in the console unit 4 and rotates the distribution gate 16 left and right in the horizontal plane to change the conveyance direction of the conveyance conveyor 15. Switching to three directions, the acceptable product that is directly conveyed to the downstream on the conveyor 15 and the foreign matter mixed product and the non-quantity product (non-weight standard product) discharged to the left or right in the middle of the conveyor 15 are sorted.

According to the second embodiment, in addition to the effect of the first embodiment, it is possible to automatically separate the acceptable product, the foreign matter-containing product, and the unquantified product. In addition, since the foreign matter-containing product is labeled with a label to that effect, it is possible to eliminate the possibility that the foreign matter-containing product will be erroneously mixed with an acceptable product or a non-weight standard product in a subsequent process. it can.

In the second embodiment, the non-constant product is explained as an example, but it is obvious that the same can be applied to the constant product.
